Grease cellar



Nov. 22, 1932.

A. 1 y MQLERl GREASE GELLAR' Original Filed May 2l, 1927 Figa" y l QM @WY l with four corner lugs 32-32, each of which has an aperture 33 therethrough, so that the grease cellar may be supported in position by a pair of elongated bolts 34, which are passed through said lapertures 33 and corresponding alined apertures in the lower portions of the jaws 10 of the driving box. The bolts 34 may be held in position by vcotter's 35. To brace the corner lugs, arcuate corner webs 36 are provided uniting the same with the central portion of the casting and alsorvertical reinforcing webs 37 are provided,- uniting the lugs and the laterally extended sections of the side' chambersV as clearly indicated in Figure 4;. In order to further reinforce Vthe cellarrcasting and brace the same to prevent crushing or collapse thereof, which Vmight' otherwise occur,rdue to the tendency of the depending arms of the driving box to approach each other in service, a plurality of transversely .extending depending bracing ribs 40 are provided on the bottom of thel casting between each pair of lugs 32-32 land formed integraltherewith. VAs clearly shown *Y in Figures 2, 3 and 4, four such ribs are preferably employed, arranged in pairs, the members of eachpair being spaced apart so as to l*accommodate the corresponding securing boltl cellar.

34. therebetween. e With this arrangement, it will be observed that air is permitted to circulate both verticallyr between the pairsrof corner lugs, oneach side of the casting and also longitudinally of the cellar, it being noted in this connection that the movable or displaceable plate 29 yis made narrow soas to leave amplel openings at either side thereof for 'the circulation of air lengthwise ofthe Thev greasev orother lubricant dispensed from thecentral chamber will be applied to VVthe journal and carried around by the latter, and as the carried over or wastelubricant is brought down by the descending side of the journal, it will be collected `in Vone or the other of the collecting chambers 13, de-Vv depending upon the direction of rotation of f in.k As the vwaste lubricant is accumulated inthe side chambers, the .latter will lill and as more waste lubricant is collected, pressure will be set up in the retained waste lubricant` so that, by providing a plurality of holes or vent openings 38-38, distributed over the bottoms of the collecti-ng chambers, the lubricant which is ina plastic or 'semi-plastic .'stapte, will be expressed or extruded therethrough under pressure sothatthe grease cellar is self-clearing as will-be obvious. As

the wastegrease o r lubricant-is expelled, it

will drop down between the separated corner lugs of the cellar and thence to the roadway, thus obviating the necessity of attention to the collection of waste grease or lubricant. The collected waste lubricant will also, after the cellar has been in use a very short time, provide a lm or covering for the vent openings 38 so as to close the latter against the admission of dust that might otherwise possibly be forced upwardly therethrough and into contact with the journal. The provision of a relatively narrow' dispensing chamber permitting the use of a narrow grease cake, has been found to be very economical as compared with the more common grease cellars having a single wide chamber and correspondingly vwide grease cake and dispensin'g'plate, l g

It is further pointed out that my improved construction of grease cellar :casting having air'circulating passagesA assures adequate cooling of the same, thereby effecting a great 're-` rduction in the amountl oflubricating agent consumed, without sacrificing strength, inasmuch as the transverse reinforcing ribs l0 between the lugs 32 thoroughly brace the casting against collapse, thus providing am; exceptionally rugged construction which effectively prevents crushingv of the cellar due to the tendency of the depending arms of thedriving box vto approach each other when therboxbecomes heated during operation iIr-ij service. 95 Y With my improvements, it will beseen that the only attention that need be'paid tothe cellar is that of .maintaining the supply of grease in the central chamber and ythis may@ be replenished by simply displacing the end plate 29 and` without removing the-grease cellar from the driving box.

Although I have herein shown and described what I "now consider the preferred?` vmanner of vcarrying out myy invention, the same is merely illustrative and I contemplate all changes and modifications that come within thescope of the claims appended hereto.,

I claim: V 1 f p l.Y A lubricating. cellar for a locomotive driving box, said cellar having a vdispensing chamber and a collecting chamber, the latter having spaced vent openings ina wallthereof leading to the exterior of the cellar througlr which the waste lubricant in a plastic state is adapted Vto be extruded.

2. A lubricating cellar for locomotive drivl ing boxes, said cellar having a lubricant-dispensing chamber and a waste lubricant col-1B lecting chamber, the e latter beingv open on 12 its upper side with the opening presented to the journal and having a bottom `wall provided at different zoneswith openings extending therethrough to the exteriorof the cellargl whereby the collected waste lubricant is extruded while ina plastic state.

Yeo

of said collecting chambers having a plurality of separated vent openings in a wall thereof leading to the exterior of the cellar and through which the collected waste lubricant is adapted to be discharged by extrusion While in a plastic condition.

4. A cellar of the character described for locomotive driving boxes, said cellar having a central relatively narrow, dispensing chamber and a relatively shallow` collecting chamber on each side thereof, each collecting chamber being open at its top with the opening presented to the journal and having a bottom wall,` the latter being perforated to provide discharge openings distributed throughout the same, leading to the exterior of the cellar to discharge the collected waste lubricant by extrusion while in a plastic condition, below said chamber.

5. A grease cellar for locomotive driving boxes comprising: a casting provided with a central dispensing chamber and shallow side collecting chambers and integrally formed corner attaching lugs, each of said side chambers being provided with a bottom wall with openings therein leading to the exterior of the cellar, said openings being distributed throughout the area of said wall whereby the waste grease in a plastic state collected in said side chambers is adapted to be extruded through said openings.

In witness that I claim the foregoing I have hereunto subscribed my name this 17th day of May, 1927.
